In short
The Merchant Guru helps B2B peptide suppliers that sell exclusively to licensed healthcare professionals get a peptide merchant account. Our program is built for gated, NPI-verified catalogs of FDA-approved peptide products and substances on FDA’s 503A Category 1 bulk drug substances list. Research-use-only sellers don’t qualify. Because we underwrite up front, we don’t turn accounts off for an unsupported business type.
Updated October 2026
Say the word “peptides” to most processors and the conversation ends there. We get it. The space is full of “research use only” websites that sell to anyone with a credit card, and banks have learned to steer clear.
But there’s a very different kind of peptide business: suppliers that sell only to prescribers, clinics and 503A pharmacies, behind a login, with every buyer verified. That’s who this program is for, and it’s built around exactly what the bank needs to see.
No hidden fees. Terms clearly outlined in the merchant agreement. Because we underwrite up front, we don’t turn accounts off for an unsupported business type.

If you sell only to licensed providers and a processor just closed your account or is holding your funds, don’t wait on the form. Call us for a straight read on your options.
This program is for peptide businesses whose customers are healthcare professionals, not the general public. You’re a fit if you sell to:
What doesn’t fit this program: “research use only” peptides, sales to consumers, and peptides that aren’t FDA-approved products or on FDA’s 503A Category 1 list. If that’s your model today, call us anyway. We’ll tell you plainly what would need to change.
Underwriting reviews three things: your business model, your buyer controls and your supporting documents. Here’s the business model side, and why each piece matters.
| Requirement | What it means | Why the bank cares |
|---|---|---|
| Gated website | Product pages, pricing and checkout sit behind a login. Public visitors see only your homepage, company information and registration page. | It proves you aren’t selling to the public. |
| Eligible products only | Every SKU is an FDA-approved peptide product or a substance on FDA’s 503A Category 1 bulk drug substances list. No “research use only” or unlisted peptides. | It keeps your catalog inside what federal rules allow. |
| NPI-only customers | You approve only buyers with a valid, active NPI number, such as licensed prescribers, clinics and 503A pharmacies. No consumer sales. | It shows every buyer is a healthcare professional. |
| Documented sourcing | A supplier agreement and invoices that show where your products come from. | It connects your inventory to a legitimate supply chain. |
| Compliant marketing | No disease or treatment claims, no consumer-facing ads and no “research chemical” language on your website. | Claims and consumer ads are what card brands and regulators flag first. |
Catalog monitoring: FDA’s lists change. If a peptide moves off Category 1, it comes out of your catalog. Building that check into your routine keeps your account in good standing.
A 503A pharmacy can compound with a bulk substance only if it meets certain conditions. For many peptides, the deciding factor is FDA’s interim bulk drug substances lists:
| FDA status | What it means | Can it be in your catalog? |
|---|---|---|
| FDA-approved product | An approved drug with an approved label | Yes |
| 503A Category 1 | Under evaluation, and eligible for compounding in the meantime | Yes |
| 503A Category 2 | Flagged by FDA for significant safety concerns | No |
| Not on any list, or “research use only” | No pathway for compounding or patient use | No |
What changed in 2026: On April 15, 2026, FDA removed a group of peptides from Category 2. That did not move them to Category 1. In July 2026, FDA’s Pharmacy Compounding Advisory Committee reviewed seven peptides, including BPC-157 and TB-500. The committee’s votes are advisory, and FDA still has to act before any of them are added to Category 1.
Our take: more change is likely. Until FDA updates the list, your catalog follows the current version, and it’s business as usual. When the list changes, we’ll help you update your catalog the right way.
This is general information, not legal advice. Confirm your obligations with qualified counsel. See FDA’s bulk drug substances used in compounding page and the July 2026 advisory committee meeting.
You’ll need a written verification process that matches your live website. Underwriting will log in with a test account and check that the controls actually work.
STEP 1
Buyer name, practice or business name, address, phone, email and NPI.
STEP 3
Confirm the provider’s state license is active, where applicable.
STEP 4
Keep products and purchasing locked until a person reviews and approves the account.
STEP 5
Ship only to the verified practice, clinic or pharmacy address.
STEP 6
Store every verification result so you can provide it on request.
STEP 7
Re-verify periodically, and close accounts if an NPI or license lapses.
Your website is the first thing underwriting reviews, and they’ll look at it twice: once as the public, and once logged in.
Your homepage, company information and a registration page for healthcare professionals. No product pages, no pricing and no checkout.
Your catalog, pricing and checkout, available only after a buyer’s NPI and license are verified and approved.
Describe your company and your service to professionals. Leave out disease or treatment claims, consumer ads and “research chemical” wording.
Things that help: a clear registration flow, a written KYC summary that matches the site, and supplier invoices that line up with your bank deposits.
Things that raise flags: public pricing, products in the catalog that aren’t eligible, and any “research use only” language.
Practices and pharmacies pay differently than consumers. Your setup should match how your buyers actually order.
Online checkout inside your gated catalog for verified buyers.
A lower-cost way to accept larger B2B orders. Learn more
Same day to 48-hour funding options for approved merchants.
Backup accounts, done the right way: a second fully disclosed peptide merchant account with another bank, so one review doesn’t stop your sales. Splitting sales to stay under card brand limits breaks the rules, so we never set accounts up that way.
A structured review, so there are no surprises after you go live.
Ready? Start your application or call (818) 731-2227.
A complete file keeps your review moving. Gather these before you apply:
Before you submit: send one complete package. Make sure names, addresses and your EIN match across every document, use full PDF statements rather than screenshots, highlight the deposits that match your three sample invoices, and keep the test login active until you’re approved.
We’d rather set you up once and correctly than quickly and twice.
We don’t turn accounts off for an unsupported business type, because your business is reviewed before you go live.
Requirements written for gated, NPI-verified catalogs, not a generic high-risk checklist.
We check your website, KYC steps and documents before the bank sees them.
A second fully disclosed account, so one review doesn’t stop your sales.
One consultant who knows your file and picks up the phone.
Peptides are one of the fastest-moving categories I see, on the business side and the regulatory side. Most of the calls I get are from sellers who were approved by a processor that never asked who their customers were, then shut down a few months later.
This program works the other way around. We start with your buyers, your catalog and your website, and we only submit when the file is ready. If you sell to licensed professionals and you’re willing to keep it that way, I’d like to help you build something that lasts.
If you want a straight read on whether you fit, even if the answer is “not yet,” give me a call.

Yes, if you sell business to business. Our program is for suppliers that sell only to licensed healthcare professionals through a gated website, with a documented process for verifying every buyer.
No. Research-use-only and unlisted peptides don’t qualify. Every product in your catalog needs to be an FDA-approved peptide product or a substance on FDA’s 503A Category 1 bulk drug substances list.
Not under this program. Buyers need a valid, active NPI number, such as licensed prescribers, clinics and 503A pharmacies.
It’s one of FDA’s interim lists of bulk drug substances under evaluation for use by 503A compounding pharmacies. Substances in Category 1 can be compounded while FDA evaluates them. Category 2 substances have been flagged for safety concerns.
Not as of October 2026. FDA removed BPC-157 and other peptides from Category 2 in April 2026, but that isn’t the same as adding them to Category 1. FDA’s advisory committee reviewed BPC-157 in July 2026, and FDA still has to act. Until it’s on Category 1, it can’t be in your catalog.
Look the buyer up in the NPPES NPI Registry and confirm their name and address match what they gave you. Then check their state license where applicable, approve the account manually and ship only to the verified practice address.
Your product pages, pricing and checkout do. Public visitors should see only your homepage, company information and registration page.
Remove it from your catalog. Building a regular check of FDA’s lists into your routine keeps your account in good standing.
Owner ID and SSN, your EIN letter, formation documents, three months of business bank and processing statements, a voided check, your website with an active test login, a supplier agreement, three sample invoices and a one-page KYC summary.
It depends on how complete your file is. Same-day approvals are available on a case-by-case basis and are restricted to certain industries. One complete package with matching documents keeps your review moving.
We underwrite up front, so we don’t turn accounts off for an unsupported business type. Your account still needs to follow card brand rules and the program requirements, and we help you do both.
No, and be wary of anyone who does. Every bank makes its own decision. What we can do is review your business honestly and help you submit the strongest compliant file possible.
